6 0

Answer:

4x^2 - 1 = 0

Step-by-step explanation:

x = 1/2, x = -1/2

2x = 1, 2x = - 1

2x - 1 = 0, 2x + 1 = 0

( 2x - 1 )( 2x + 1 ) = 0

4x^2 - 1 = 0

djyliett [7]

Please help me with number 7
Wittaler [7]

"twelve decreased by twice a number"   --->   12 - 2x

"8 times the sum of number and 4"   --->   8(x + 4)

12 - 2x  =  8(x + 4)

12 - 2x  =  8x + 32                    (distributive property)

12        =  10x + 32                   (add 2x to both sides)

-20       =  10x                           (subtract 32 from both sides)

x  =  -2                                      (divide both sides by 10)

That's answer.
